Square peg, round hole

You know that game with the different shaped pegs and the different shaped holes? The Monkey is not especially good at it. He's better when he's fresh, not tired. And he can get a peg through if it happens to start at or near the correct hole. But if he gets one through, it's random chance as far as I can tell.

I'm not concerned: the kid is pretty good with his hands and shapes and things. But at 21 months, I was expecting a little more.
